Detective Superintendent Steve Holahan says so far two people have been charged with trafficking and producing dangerous drugs.

Police say further arrests are likely.

Detective Superintendent Holahan says Queensland laws ban many of the compounds in the synthetic drugs.

"We've got 22 compounds scheduled - actually listed," he said.

"We've got an extended definition of a dangerous drug which outlines that if a substance is an analog, a derivative or it has a substantially similar chemical structure and substantially similar pharmacological effects, it is a dangerous drug by definition."

He says it is important to get the drugs off the streets before the start of Schoolies this weekend.

"These substances that are often portrayed as legal highs and safe products have some very real dangers," he said.

"We have anectodal evidence recently in relation to incidents where people have died, and sustained serious injuries in other instances."

Detective Superintendent Holahan says some of the drugs contain a dangerous compound called Alpha-PVP.

"It's a psychotic-type substance and people suffer from their body overheating, psychotic events, very irrational behaviour, often leading to violent incidents where they cause significant destruction and often injure themselves as well," he said.
